' BERTIE B. MOSS, OF PEKIN, INDIANA.

NUT-LOCK.

SPECIFICATION forming part of Letters Patent No. 738,052, datedSeptember 1, 1903.

Application filed June 22,1903. Serial No. 162,617, (No model.)

To all whom it may concern:

Be it known that I, BERTIE B. Moss, a citizen of the United States,residing at Pekin, in the county of lVashington and State of Indiana,have invented certain new and useful Improvements inNut-Locks; andI dohereby declare the following to be a full, clear, and exact descriptionof the invention, such as will enable others skilled in the art to whichit appertains to make and use the same, reference being had to theaccompanying drawings, and to the figures of reference marked thereon,which form a part of this specification.

The object of this invention is to produce a nut-lock which will serveto lock the nuts and bind the bolts of the joints of railroadrails. Inaddition to a washer having a tongue which turns down over the nut itincludes a washer plate which is jammed between the base of thefish-plate and the bolt and which serves to bind the bolt tightlyagainst the top of the hole in the fish plate. I have found that theloosening of the bolts of railwayjoints is chiefly caused by theup-and-down motion of the bolts and resulting wear of the fish-plate andnut due to vibration caused by the passage of trains.

In the accompanying drawings, Figure l is a side elevation of theinvention as applied to arail-joint, and Fig. 2 is a verticalcrosssection thereof.

Referring specifically to the drawings, 6 indicates the rail, and 7 thefish-plates, which have bottom flanges 7 which overlie the base of therail.

8 indicates the bolt through the rail and fish-plate, and 9 the nutthereon.

' At 10 is a thin flexible nut-lock washer having a series of tongues10, which may be bent down upon the side of the nut to prevent the samefrom turning. To prevent the washer from turning, its base portion 10 issquared or cut off straight to fit against the flange of the fish-plate,so that it can not be turned on the bolt. Between said washer and thenut is another heavy, thick,and rigid Washer-plate 11, the object ofwhich is to jam the bolt against the top of the bolt-hole through thefish-plate and to prevent any relative move ment between the bolt andthe fish-plate. The lower end of this plate 11 bears against the flangeof the fish-plate, and it is cut of such length that it produces a tightbind and upward pressure against the bolt when it is jammed in betweenthe flange of the fish-plate and the bolt. In other words, it lifts andstrains the bolt upwardly against the top of the bolt-hole in thefish-plate. The nut holds this washer in place, and as long as the nutis on the fish-plate and bolt are firmly bound together and relativemovement or vibration thereof is prevented. Such movement is whatproduces wear and loosening of the nut, and the avoidance thereof isadvantageous.

hat I claim as new, and desire to secure by Letters Patent, is-

1. The combination with the bolt, nut, and fish-plate having a flange atthe lower edge, of a rigid washer-plate on the bolt under the nutslightly longer than the distance from the bolt-hole to the flange, sothat it is jammed between the flange and the bolt, and means to lock thenut.

2. The combination with the bolt, nut, and fish-plate having a flange atthe lower edge, of a rigid washer-plate on the bolt under the nutslightly longer than the distance from the bolt-hole to the flange, sothat it is jammed between the flange and the bolt, and a flexiblenon-rotatable washer on the bolt having a locking-tongue bent againstthe side of the nut.

In testimony whereof I affix my signature in presence of two witnesses.
